SAMUEL B. BILGER, OF SO'UDERTON, PENNSYLVANIA.

HOISTING APPARATUS.

To all whom it may concern:

Be it known that I, SAMUEL B. BILGER, a citizen of the United States, residing at Souderton, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Hoisting Apparatus, of which the following is a specification, reference being had to the accompanying drawings. 1

This invention comprehends certain new and useful improvements in hoisting apparatus, and the invention has for its primary object a simple, durable and efficient c011- struction of window hoist designed for use in raising pianos or the like up to and in through the windows of upper story rooms.

The invention also has for its object a very strong and simple construction of window hoist, the parts of which are so arranged and formed that they may be easily constructed and assembled and applied to the frame of a window or the like, and which are so connected together that proper adjustment may be easily effected and the parts disconnected one from the other so that the entire device may be easily carried from place to place in knocked down condition. V.

The invention also has for one of its objects a device of this character which is so constructed and arranged that the full width of the window may be utilized for passing the piano or the like therethrough. And the invention also aims to generally improve this class of devices and to render them more useful and commercially desirable.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing in which,

Figure 1 is a front elevation of a window hoist constructed in accordance with my in-v vention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a horizontal section on the line 3-3, of Fig. 2. Fig. 4 is a vertical transverse section, partly in elevation, the section being taken on the line 4:4, of Fig. 2, and, Fig. 5 is a detail section on the line 5-5, of Fig. 2.

Specification of Letters Iatent.

Serial No. 685,285.

Corresponding and like parts are referred to in the following description and desig nated in the accompanying drawing by like reference characters.

My improved window hoist includes a head frame which embodies an inner cross bar 1 which is constructed in upper and lower sections designated 2 and 3, respectively, the upper section being preferably in the form of an angle bar and the lower section 3 being preferably in the form of a flat bar secured to the upper section 2 by bolts 4 or similar fastening devices. The sections 2 and 3 are held spaced from each other, preferably by washers or thimbleso encircling the bolts 4, whereby a space is provided between the upper and lower sections for the passage of tie rods 6. The head frame also includes an outer cross bar 7 which is, in the present embodiment of the invention, constructed of angle metal and which is formed with apertures 8 through which the outer ends of the tie rods 6 are passed.

The tie rods 6 are formed with screw threads 9 designed for engagement by tightening members 10 which are mounted thereon and which are provided with handles 11 by which they may be easily manipulated. At this point, it will be understood that the head frame of the device is secured within a window-frame or casing at the top of the same, the cross bar 1 being disposed within the room and being preferably provided with increased bearing surfaces that are formed by blocks or boards, whereby all injury to the wall paper and plaster will be prevented. The outer cross bar 7 is disposed on the outer side of the window-frame and the two cross bars are clamped tothe outer and inner sides of the window-frame by tightening up the members 10 on the tie rods 6 in an evident manner.

The tie rods 6 are formed at their outer ends with eyes 12 which are pivotally con nected to corresponding eyes 13 formed on the inner ends of link rods 14. These link rods have welded thereto, any desired number of links 15 which are designed to be received between the laterally spaced ears 16 of collars 17 that are secured to standards 18 near the upper ends of the latter. The ears 16 are transversely apertured, as shown, to receive locking pins 19 that are preferably secured to the collars by relatively short chains 19 so as to prevent the pins from becoming lost. It will thus be understood that the standards 18 may be held at different angular adjustments or inclinations relative to the window-frame, as required, by passing certain of the links 15 in between the apertured ears 16 and by then passing the pins 19 in through the apertures of the ears and said links so as to securely hold the parts in the desired adjusted position.

The upper ends of the standards 18 are connected together by a cross bar 20 which is formed with a clevis 21 or the like, from which block and tackle are designed to be suspended, whereby the tackle may be secured to a sling or truck which is designed to be secured to the piano to be lifted. The lower ends of the standards 18 are held by bolts 22 or similar fastening devices in sockets 23 that are formed in base or foot members 24 that are designed for engagement with the window-sill at the outer side thereof. The sockets 23 of the foot members 24 are laterally offset, as clearly illustrated in the drawing, whereby the rods or standards 18 will be held entirely outside of the lateral planes of the sides of the window, so as to leave the entire width of the window for the passage therethrough of the piano or the like being hoisted. It will thus be understoodthat these foot members are made in rights and lefts.

I preferably employ in connection with the parts hereinbefore described, a swing 25, the suspension cables 26 of which are swung from the cross bar 20, said cables being connected at their lower ends to a saddle or cross bar 27 which may be disconnected at one end from the cable so as to be passed underneath the piano truck or sling and assist in holding the parts steady. It is to be understood, however, that my invention is not limited to the use of any particular form of construction of swing and that various changes may be made in this and other parts of the apparatus without departing from the scope of the invention, as defined in the appended claims.

From the foregoing description in connection with the accompanying drawing, the operation of my improved piano hoist will be apparent. In the practical use of the device, the head frame is secured to the top of the window-frame or casing, as above described, and the link rods 14 are connected at the required adjustment to the standards 18. The foot members 24 i are securely braced upon the window-sill at the outer side thereof. Thus, the entire hoist is securely held in position extending outwardly from the window-frame or casing and the piano or other device to be hoisted may be easily raised to the window and passed therethrough into the room.

lVhat I claim is 1. A window hoist, including a head frame, embodying an inner cross bar con structed in upper and lower sections connected together in spaced relation to each other, an outer cross bar formed with apertures, threaded tie rods passed inwardly through said apertures and formed at their outer ends with eyes, said tie rods being formed with screw threads and passing in between the upper and lower sections of the first named cross bar, tightening members screwing on the inner extremity of said tie rods, links having eyes pivotally connected to the eyes on the outer ends of the tie rods, standards adapted to extend upwardly and outwardly from the sill of the window frame, foot members having sockets supporting the lower ends of said standards, a cross bar connected to the upper ends of said standards and adapted to support a block and tackle, and adjustable and detachable connections between said links and said standards.

2. A window hoist, including a head frame, embodying an inner cross bar constructed in upper and lower sections, bolts connecting said sections, washers encircling said bolts thereby spacing the said upper and lower sections, an outer crossbar formed with apertures, threaded tie rods adapted to pass inwardly through said apertures and formed at their outer ends with eyes, said tie rods being formed with screw threads and passing in between the upper and lower sections of the first named cross bar, tightening members screwing on the inner extremity of said rods, links pivotally connected to the outer ends of said tie rods, standards adapted to extend upwardly and outwardly from the sill of the window frame, a cross bar connecting the upper ends of said standards and designed to' sup port a block and tackle, foot members adapted to engage the sill of the frame, the lower ends of said standards connected to said foot members, and an adjustable connection between said standards and said links.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
